The value of serological tests for syphilis in atypical genital ulcer disease.

A 45-year-old heterosexual man presented with phimosis three weeks after arriving in this country from India. Examination under anaesthesia and circumcision revealed a large ulcer on the ventral aspect of the penis around the fraenum. Histopathological examination of a biopsy taken from the ulcer revealed granulation tissue with inflammatory cell infiltrate. Specific and non-specific serological tests for syphilis carried out four weeks after the initial presentation showed high titres. The importance of serological tests for syphilis in genital ulcer disease, especially in atypical presentations, is discussed.
